    Abstract: A micro-fluid ejecting head for use in a micro-fluid ejecting apparatus includes a plurality of micro-fluid ejection devices, a plurality of driver devices for driving the plurality of micro-fluid ejection devices, and a nonvolatile programmable memory matrix. The memory matrix contains embedded programmable memory devices for storing information related to operation of the micro-fluid ejecting head. The memory matrix is configured to communicate with a controller which is external of the micro-fluid ejecting head. The information stored in the memory matrix may include identification information for the micro-fluid ejecting head, alignment characteristics of the micro-fluid ejecting head, information regarding properties of fluid used by the micro-fluid ejecting head, fluid level information, and fluid use information. The external controller accesses the information stored in the memory matrix and controls the plurality of driver devices based on the information accessed from the memory matrix.

    Abstract: An ink jet print head identification system for providing print head identifying information to the electronics of an ink jet printer includes one or more parallel load, serial out, dynamic shift registers (50 A-D) integrated into a print head chip having a plurality of address lines interconnecting the printer electronics and print head electronics. Each shift register is programmed or encoded with a single digital bit. In one embodiment, a voltage pulse (load signal) (70) received on a single chip address line by a plurality of shift registers (50 A-D) loads the input of each encoded register with the register's own encoded bit. Two of the address lines (72,74) provide each of the registers with successive sequential clock signals (1,2) to serially shift the encoded information to an output device (80) where the print head identifying information is read by the printer electronics. Other embodiments of the invention may employ any number of encoded registers independently of the number of available address lines.
